For this, the scanning unit 171 includes a plurality of scanners respectively corresponding to a plurality of contents sources, and scans and searches for contents in each corresponding external device.
For example, the scanning unit 171 may include a USB File Scanner, a DLNA File Scanner, and a Metadata Scanner, which respectively correspond to a USB device, a DLNA server, and a media server.
In more detail, the USB file scanner accesses a USB device connected to the image display device 100 through a USB Plug in/out Manager, and searches for contents stored in the USB device.
Additionally, the DLNA file scanner receives an event message through a DLNA status manager using UpnP when a network between the image display device 100 and a DLNA server is connected or disconnected, and searches for contents in the eDLNA server by using HTTP protocol.
Moreover, the metadata scanner receives an event message through a DLNA status manager using mDNS when a network is connected or disconnected, and searches for contents in the media server by using HTTP protocol.
Also, the control unit 140 may further include a USB DVR manager (not shown). The USB DVR manager may search for contents stored in an Electronic DataBase Management System (EDBMS).
Then, information on the searched contents may be delivered to the update management unit 172.
An MGE interface unit 136 may request the transmission of meta information on movie contents among the searched contents to the SDP server 300, and then, may receive an eXtensible MarkUp Language (XML) file including the meta information from the SDP server 300.
Furthermore, a parsing unit 137 parses the received XML file in order to obtain meta information on the movie contents, and then delivers the meta information to the update management unit 172.
Accordingly, the update management unit 172 obtains information on the contents searched from a plurality of contents sources and meta information matching some of the contents (for example, movie contents), and the matched contents information and meta information may be stored in the storage unit 140 through the storage management unit 173.
The contents list management unit 174 constructs a contents list by using the contents information and meta information stored in the storage unit 140, and the constructed contents list is delivered to the display unit 180 in order to be displayed on the screen 600 of the image display device 100.
According to an embodiment, the scanning unit 171 confirms whether contents information on each of a plurality of contents sources is changed (for example, contents addition, deletion, or modification) by using a plurality of scanners, and searches for all contents again in a corresponding contents source when the contents information is changed in order to deliver a contents list to the update management unit 172.
Moreover, the update management unit 172 obtains information on the changed contents by confirming the contents list delivered from the scanning unit 171. In addition to stored time information, the changed contents information may be stored in the storage unit 140 through the storage management unit 173. The stored time information may represent a time at which the contents information is stored in the storage unit 140.
In this case, the contents list management unit 174 may update a previously-constructed list according to recently added, deleted, or modified contents information by using the contents information and stored time information stored in the storage unit 140.
Additionally, when contents in the contents list are played, time information on the contents playback stop may be stored in the storage unit 140, and accordingly, the contents list management unit 174 may update a previously constructed contents list according to recent playback information.
According to an embodiment, the image display device 100 and the SDP server 300 may communicate with each other through Representational state transfer (REST), and the MGE interface unit 136 of the image display device 100 may transmit the name of a contents file to the SDP server 300 through HTTP, thereby requesting the transmission of meta information on corresponding contents.
For example, the meta information transmission request from the MGE interface unit 136 of the image display device 100 to the SDP server 300 may have a format such as ‘http://IP address/specific path?query=filename (including extension)’.
Then, the following is the case that the image display device 100 requests meta information on movie contents having an ‘avartar.avi’ file name to the SDP server 300.
http://x.x.x.x:8080/SmartShareModule/api/search.x ml?query=avatar.avi
Referring to
Moreover, a search engine 340 may search a DB 350 for meta information on corresponding contents by using the contents title extracted from the Contents Title extracting unit 330.
According to an embodiment, the search engine 340 reads updated meta information from the DB 350 periodically, and then indexes the read meta information in order to store it in a memory (not shown).
In this case, the search engine 340 does not directly search the DB 350 for the contents title extracted from the Contents Title extracting unit 330, but searches the meta information by first using indexing information stored in the memory, so that search speed and accuracy on meta information may be improved.
A Metadata Aggregation System (MAS) 360 receives meta information on various contents periodically from SPs, and parses the received meta information to store it in the DB 350.
Additionally, a Matching Score calculating unit 320 may detect meta information that is the most corresponding to a corresponding contents file from the search results inputted from the search engine 340, and for this, a Levenshtein distance algorithm may be used.
Then, the MGE interface unit 310 constructs the meta information detected by the Matching Score calculating unit 320 with XML, and transmits the XML to the image display device 100 through HTTP, so that a response to the metal information transmission request from the image display device 100 may be completed.
Referring to
For example, the MGE interface unit 310 constructs the XML of
The method of managing contents according to the present invention can also be embodied as computer readable codes on a computer readable recording medium.
